IMPROVEMENT-IN SEED AND GRAIN-:SEPARATORS.

The Schedule referred to in these Letters Patent andmaking part of the earns.

panying drawings, and to the letters of reference marked thereon, which form a part of this specification.

- The nature of my invention consists in the construc-- tion and general arrangement of a grain and seed-separator, as will hereinafter be fully set forth.

In order to enableothers skilled iu-the art to which my invention appertains, to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which Figure 1 is a longitudinal vertical section, and

Figure 2 is a plan view of my machine.

A represents the framework of my machine, in the upper part of which is the hopper B.-

The hopper-board G is notched on the .under side, and held in any position desired, by means of the spring D, which is secured to the hopper, and the inner end of which enters into any one of the notches on the hopper-board, and thus the feed can be easily regulated. v

Within the frame A is placed the sicve-frame-E, which rests upon rollers, a a, under its rear end, and at its front end upon rollers 12 b, which may he raised or lowered atwill, so as to change the incline or pitch of .the sieves in the frame E.

The rollers b b are place on the inner ends of setscrews 1 F, which pass through slots in :the sides of the frame A, thus admitting of the raising andlower- The sieve-flame E is, at the rear end, by a partition, 0, divided ofi, forming a V- shaped chamber, G, with a sliding door, (I, on the rear side, for emptying grassseed.

The chamber G is covered by the hopper-screen H", directly under the hopper, through which screen the grass-seed passes into the chamber below.

In the other portion of the frame E, that is, in front of the seed-chamber G, in grooves in the sides of the frame, are inserted the sieves I I, which are held in place by a rod, c, on each side, that passes through said sieves and the frame.

Under the frame E is another frame, J, with sieves K K inclining in the opposite direction, thelower end of which frame rests upon a --cross-bar in the main frame A.

The frames E and J are, by means of a hook, L,

seeds.

connected with a lever, M, on a rocking shaft, N, which has its hearings in arms 0 O, pivoted to the sides of the main frame A, and held at any height desired, by means of slotted and curved plates 1? P. v

These plates are secured to the frame A by means of set-screws R R, which thus allow the rocking shaft N to be raised and lowered at will, thereby also rais- -'ing or lowering the sieves.

Through the rocking shaft N, the sieves receive their mot-ion and the rocking shaft itself receives its mot-ion by means of a pitmau, S, which connects acrankpulley, T, with a lever, U, on the end-of the rocking shaft. 1

The fan W is constructed in the following manner:

On the centre of the fan-shaft f is one set of arms,

g g, supporting the wings It h, which enables the wind to pass within the drum without obstruction, giving thefan greater power.

The'crank-pulley T is by a belt, It, connected with a pulley, X, on the end of a shaft, Y, whichis placed directly under the hopper B, and is provided with raketeeth, it, for the purpose of separating and throwing out chaff and straw fromgraiu and allkinds of smaller The pulley -X may be connected with another pulley, Z, to work an additional rake, when required.

Ou-one end of the fan-shaft, f, is a cog-wheel, m,

'which gears with another larger cog-wheel, n, turned by a crank, 11, for operating the machine, or it may be operated in any other suit-able manner.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The frame E, constructed as described, with a partition, 0, to form the V- shaped chamber G, said chamber being provided with sliding door at and hope .per-screeu- H, substantially as and for the purposes herein set forth.

2. The arrangement-of the arms 0 O, slotted plates PP, and set-screwsR It, for the purpose of raising and lowering the-rocking shaft N, substantially as herein set forth.

3. The within-described arrangement of feed-board 0, spring D, shaft Y, frame E, stationary rollers a a, adjustable rollers b b, arms 0 O, slotted plates P P, and rocking shaft N, all constructed and operating in the manner and for the purpose set forth.

Intestimony that I claim the foregoing as my own, I aflix my signature, in presence of two'witnesses.
